There seem to be lots of sites launching at the moment that promise to find you cheap one way flights but not many have the professional finish of Flightlist by @ismaelyws #travel #flights

Did you spot my recent article about how to score cheap one way flights? ✈️ FlightList is my new secret tool for discovering cheap routes, within a departure date range. Plus you can also search by country/region for departures & destinations. Powerful! 💪

Cheap Flight Search Tips

Tips to help you find the cheapest flights from Houston to Knoxville (IAH to TYS).

  • Book 45-90 days before your departure date.
  • Fly during weekdays (Monday-Thursday).
  • Airfare Sales: Airlines sometimes offer huge discounts and since we take a bottom-up approach these flights will appear first in the results, so check back regularly because they don't usually last long.

Why I Built FlightList

❝As someone who works remotely & travels frequently, I always book one way flights and I'm flexible on my departure dates. I look for the best deals. Most sites require you to enter a specific departure date and clutter the page with uneccessary options, images and ads. I want something simple and minimal which allows me to search by departure date range & display a list of flights with the ability to filter according to my needs. So, I built FlightList to solve my own problem & help other travelers who may have the same frustration. It's how I imagine a flight booking site should be.❞
